The reports portal was found to be unavailable.
Both the data warehouse service and the jasperserver logs had references to database connections exhaustion, e.g:
ovirt-engine-dwhd.log:2014-02-06 19:00:24|PanvZ8|NaG6rr|EOxIEr|OVIRT_ENGINE_DWH|SampleTimeKeepingJob|Default|6|Java Exception|tJDBCConnection_1|org.postgresql.util.PSQLException:FATAL: sorry, too many clients already|1 server.log:2014-02-06 17:32:19,283 INFO [stdout] (ServerService Thread Pool -- 37) Caused by: org.postgresql.util.PSQLException: FATAL: sorry, too many clients already
A restart of the data warehouse service allowed it to continue, but the reports portal was still inaccessible.
